Struct serde::lib::core::collections::hash_map::RawEntryBuilder

pub struct RawEntryBuilder<'a, K, V, S>
where
    K: 'a,
    V: 'a,
    S: 'a,
{
    map: &'a HashMap<K, V, S>,
}

🔬This is a nightly-only experimental API. (hash_raw_entry)

A builder for computing where in a HashMap a key-value pair would be stored.

See the HashMap::raw_entry docs for usage examples.

Fields
